A co-worker of my spouse gave us a cutting from her Plumeria tree last year. It was a huge tree and the cutting was quite large, with many branches.
We potted the cutting in a container. The cutting took root and flourished.
Unfortunately, the branch points of our new Plumeria are low and as the tree grows it takes a lot of area (see the picture in the upper right).
I decided to divide the tree into three parts, by cutting the two side branches and transplanting the cuttings into new containers.
I cut the branches at an angle so to provide as much surface area as possible for roots to form.
I then dipped the cuttings into rooting hormone (see picture to the right).
The most important thing about rooting a Plumeria cutting is to not overwater. I use a soil-less potting mix of three parts Fir Bark, 1 part Perlite, and 1 part Peat Moss (
see this blog entry). This potting mix drains well.
The picture below shows the the Plumeria plants. The one in the center is the original plant.
